NATHAN WASHBURN, OF ALLSTON, MASSACHUSETTS.

CAR-WHEEL.

SPECIFICATION forming part of Letters Patent No. 258,266, dated May 23, 1882.

Application tiled October 24, 1881.

To all whom it may concern Be it known that I, NATHAN WAsHBURN,of Allston, of the county ot Suolk and State of Massachusetts, have invented a new and useful Improvement in Railway-Gar Wheels; and I do hereby declare the same to be described inthe following specification and represented in the accompanying drawings, of which- Figure 1 is a side elevation, Fig. 2 a. longitudinal section, and Fig. 3 a transverse section, of a car-wheel embodying my invention, the nature of which is defined in the claims hereinafter made.

The said wheel has a steel tire, A, a east-iron rim, B,wrougl1tirou spokes G, and a cast-iron hub, D, besides which it has arranged within the rim, and on opposite sides thereof, two

ing' the body or rim thereof', after which the said body or rim is to be cast against the inner periphery ofthe tire, and also about the bolts and rings and upon the spokes, in which case the rings and bolts will be within the tire, in

manner as shown in Figs. 2 and 3, and the spokes will be within the rim in manner as (No model.)

f represented in Fig. 2. Finally the hub is to be cast upon the spokes. The rim riveted to the tire in the process ot' casting the rim becomes strongly re enforced by the rings, and their connecting-bolts. These latter maybe screwbolts provided with heads and nuts; or each bolt may be in the form of a rivet, or may have screws on it to enter the rings.

A car-wheel made as described becomes very strong and durable, with little, it any, liability ot' its rim or tire becoming cracked or broken while the wheel may be in use.

YVhat l claim as my invention is as follows,

viz:

1. The combination ot the car-wheel body or rim and the two metallic rings, and their connecting-bolts arranged in such body or rim, substantially as set forth.

2. The combination ofthe two metallic rings, their connection-bolts, and the series ot' spokes, with the rim and hub arranged with and cast upon them, as specified.

3. The combination ofthe two metallic rings,

the steel tire with the hub cast upon. the spokes, and with the rim cast within and against the tire and upon the rings and bolts, all substnntially as set forth.
